- Angle between primary and secondary roll axes is 15 deg
- Operation in manual or program mode possible
- Alpha Range: ± 35 deg, Beta Range: ± 10 deg
- Computer controlled trajectory motion in continuous or step mode during blowdown
- Can maintain constant Alpha during a Beta sweep and vice versa
Plane of symmetry of model always maintained vertical
